Huh, where I’m from, when you order a simple coffee you’ll always get it black and then there is a little station where you can add milk, sugar, creamer yourself and the lids are also at that station. You’ll only get it ‘pre mixed’ when you order a coffee specialty like Latte or Cappuccino.

Also in my personal opinion, from a good espresso machine, percolator or even French press I like a black coffee once in a while, but drip filter coffee is only palatable with milk. Sometimes not even then.
